ROOFING-SLAB.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed April 7, 1919. Serial No. 2B8,Q85.'

To all whom it may concern Be it known that I, Annxanonn S. Srnnn, a citizen of the United States, resident of Chicago Illinois, have invented certain new and useiul Improvements in Roofing-Slabs, of which the-following is a specification.

My invention relates to shmgle units, or strips, designed when laid in a roof to simulate a plurality of individual shingles.

The invention aims to rovide from a sheet of roofing material well known, or improved, construction which is of much reater length than width a plurality of s ingle units, or strips, with a minimum of waste, and each unit of such form that when used to construct a roof in the usual way the end edges of the underlying portion of the unit Wlll register with the intact portion of all of the overlying units, or strips, and will not register with the cut-out ortion thereof, or spaces between the pro ecting ortions, or projections which slmulate the individual shingles.

The invention includes the shingle units, as will be hereinafter described and particularl pointed out in the appended claims.

e invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of a sheet of roofing material with the lines of cutting for one form of shingle unit illustrated by dotted lines.

Fig. 2 is a plan view of a section of a roofing formed by the shingle units produced in the manner illustrated in Fig. 1.

Fig. 3 is a view similar to Fig 1, showing in dotted lines the lines of severance for producing a slightly difi'erent form of shingle unit, and,

Fig. 4 is a section of a roof formed by shingle units of the character produced in the manner indicated in 3. a A strip of roofing materia of well known, or improved construction, and of materially greater length than width is designated 1 1n Figs. 1 and 2. From a strip of this character a plurality of shingle units, as will be hereinafter described, are roduced. The shingle unit, or strip, is designated 2 in Figs. 1 and 2, and 3 in Figs. 3 and 4, and in each instance it includes a front ortion comprising a plurality of projections, or tongues, 2*, 3, with interveni spaces which ma be, as shown in Fig. 2, t e same 5 size and s ape as the tongues, or which may be, as shown in Fig. 4, of considerably less size. Each units. so includes a body portion 2", 3, which is of considerably greater width than the ton e and as shown in Figs. 2 and 4 is approximately twice as wide as the tongue.

In forming a roof the units are laid in horizontal courses with the end edges of the units in each course abutting and with the courses so superimposed that the projections, or tongues, of each course will be exposed in advance of the tongues, or rejections, of the overlying course and wit the middle of the spaces between the tongues,or projections, of the immediate underlying course in register with the middle of the tongues, or the projections, of the immediate overlying course.

As the body portion of each unit is referably twice as wide as the width 0 the ton ues throughout the major ortion of a me made up of these units, one course has two courses superimposed thereupon, as

. shown in Figs. 2 and 4.

In prior practiceshingle units have been made substantially of-the construction described and have been used in constructin' roofs substantially in the manner describe and it has been the uniform practice in these articles of the prior art to have the end edges of the body portion of the units disposed substantially perpendicular to the general line of the front edge of the blank, or perpendicular to the line of each horizon- ,tal course of blanks as laid in a roof, with the result that portions of the abuttin ends of contiguous units will register wit the s aces between the projections of certain of t e overlying units.

For instance, were the end edges of the units, shown in Fig. 1, arranged perpendicular to the general line of the front edge of the unit, or perpendicular to the lines of the courses, portions of the abutting edges of the body portions -of the blanks of the lowermost course would be in register with the spaces between the projections of the blanks forming the third course.

M invention aims to insure the covering of the lines of juncture between abutti units b the intact portions of the units 0 both 0 the overlying courses, and the manner of accomplishing this ob'ect as disclosed herein consists in running e end edges of the body portions of the units at an angle less than a right angle-4nd as shown herein, at an obtuse ang e-to the'general direction of the front llnerof the unit.

For producinegi a lpl l-urality of shingles having the describ 6 er of roofing, such as that designated 1, an with a minimum of waste, I cut the units from the strip with the width of the units disposed substantially lengthwise of the strip, the length of the units being disposed substantially widthwise of the strip. The units are preferably made of, such length that a pair of the same will correspond to the width; of the strip 1 and the general line of severance forming the front and back of each unit extended other than at right a is to the Ian hwise edge of the strip. shown in ig. 1, the general line of severance is at an obtuse angle to the lengthwise ed es of the strip.

hus, each lengthwise section of the strip 1 of a width corresponding to the maximum width of the shingle unit is designed to form a blank which, when severed throu h the middle, will provide two shingle units and this line of severance is along a line parallel to the side edges of the strip 1.

As shown in Fig. 1, the outer edges of the body portions of the units willbe formed by the lengthwise edges of the strip 1 and due to the angle of the general line of severance formin the lengthwise edges of the blank the e ges thereof formed by the lengthwise edges of the strip 1, as well as the ed formed by severing the blank throng the middle, will be disposed at the desired angle to the neral line of the lengthwise edges of the lanks.

In the exemplifieation of the invention shown in Fig. 3 the same general plan for acteristic from a stri nuance severing the units from the strip 1 is followed, ut there is sli litly more waste than in the plan illustra diflerence in the shape of t e projections, or tongues, provided on the units.

Claims relating to the method herein described have been divided out from this case and included in a separate application, filed September 19, 1919.

I claim:

1. A shingle unit, or strip, adapted to be laid end to end in a roof to form a course and to have similar courses superimposed thereupon, said unit having along one ed a plurality of projections and spaces, said projections simulating a plurality of individual shingles when the unit. is laid in a roof, and a body portion of greater width than the projectlons, the end ed of said body portion being disposed at ot er than a right angle to the general line df the front edge of the unit.

2. A shingle unit, or strip, adapted to be laid end to end in a roof to form a course and to have similar courses superimposed thereupon, said unit having along one edge a plurality of projections and spaces, said projections simulating a plurality of individual shingles when the unit is laid inwa roof, and a body portion of greater width than the projections, the end edges of said bod portion'being disposed at an obtuse ang e to the general line of the front edge of the unit. 7

In testimony whereof, I afiixmy signature.
